i5 4670k will do fine for you, get an aftermarket cooler for it like CoolerMaster 212 EVO.
I would get a Corsair or Gskill CAS9 1866Mhz memory kit instead though as pricing is about the same.
PSU: There have been some sales recently on the Corsair HX750, if there still are get that instead. Close to that same price, much better quality.
Would also get an SSD for system drive. Samsung 840 Evo 250GB would do fine.
